Iran warned Israel on Tuesday that any further aggression in Lebanon will not go unanswered [1, 2].

The warning follows a period of heightened tension and recent Israeli strikes on Hezbollah infrastructure in Beirut [3, 4]. This escalation threatens the stability of a tentative peace deal between the U.S. and Iran, which seeks to lower regional temperatures and secure energy corridors.

An Iranian foreign ministry spokesperson said that "aggression will not go unanswered" [2]. The statement comes as Tehran links the implementation of its diplomatic arrangements with Washington to the status of Israeli military presence in Lebanon [1, 2].

Hossein Amir‑Abdollahian, Iran’s Foreign Minister, said that "Israel must withdraw from Lebanon if the tentative deal is to be implemented" [1]. The demand highlights a central friction point in the negotiations, as reports indicate Israel has rejected the condition of withdrawal [1].

President Donald Trump previously announced a peace pact with Iran, stating that oil will flow through the Strait of Hormuz [4]. However, the actual status of the agreement remains a point of contention among international observers. Some reports suggest fighting between Israel and Hezbollah eased significantly on Monday [3], while others indicate the deal remains in the balance as strikes continue [5].

Iran maintains that Israeli actions in Beirut violate the conditions of the tentative U.S.–Iran peace deal [3, 4]. The Iranian government continues to demand a full Israeli retreat from Lebanese territory as a prerequisite for further diplomatic progress [1, 2].

"Aggression will not go unanswered."

The tension underscores a fundamental disconnect between the U.S.–Iran diplomatic track and the operational realities on the ground in Lebanon. While the U.S. seeks a broad regional stabilization to ensure energy security, Iran is using the deal as leverage to force an Israeli military withdrawal. The contradictory reports regarding the deal's status suggest that while a framework may exist, it lacks the enforcement mechanisms to stop tactical strikes between Israel and Hezbollah.
